Phoenix Contact’s Quint 20+ power supply line includes a single-device solution that meets functional safety applications up to safety integrity level (SIL) 3. The Quint 20+ power supply has an integrated decoupling MOSFET and double overvoltage protection circuitry to meet rigorous SIL 3 safety regulations without the need for external redundancy. The functional safety approval allows the QUINT 20+ power supply to be used in applications up to SIL 3, according to IEC 61508. The safety function is to limit the output voltage to 30 Vdc, and if higher, to switch off within 20 milliseconds. The safe state is no output voltage. Designed with double overvoltage circuitry, the QUINT 20+ power supply also has a hardware fault tolerance (HFT) of 1.
